actor: Add pivot point

Browse Source 
The pivot point is a point in normalized coordinates space around which
all transformations revolve.

It supercedes the anchor point and the per-transformation center points
as well as the gravity settings, and tries to sort out the mess that
is the modelview matrix set up in ClutterActor.
